Engineering, consulting, strategy


We collaborate with our clients to achieve the effective and efficient implementation of the culture of sustainability.

With a systemic vision and a transversal approach, ERF offers innovative concepts and practical and effective solutions in energy and environmental consulting based on the generation of sustainability thinking. As an active partner of the city of Barcelona for twenty-five years, it has contributed to the urban and sustainable transition of the city. From its headquarters in Barcelona, ERF acts "glocally" with an action-oriented international perspective.


We like to network. In each project we tackle, if necessary, we combine our vision with other professionals specialising in urban planning and architecture, energy and environmental consulting, construction, carbon markets, hydrogeology, biodiversity, economics and other disciplines required for the project. Similarly, we are pleased to share our capabilities with other consulting firms, professionals and academia in order to provide a socio-environmental perspective to transformative projects.


We are an energy, environmental, territorial and urban consultancy; a certified energy efficiency engineering company and a sustainability and climate strategies office, with strong synergies between the different areas of work and experience.

Get up to speed on climate action!
